either way, i am tryin to be a bit different and not go vtec, and also when you have a b18a1 head and a vtec head both completely built up to the top, there isnt much of a difference in hp... unless some has the air flow specs of both heads totally built up to show me that the vtec would outflow a b18a even with oversized valves and a p&p and 5 degree valve angle job
